I have created a 3D bezier curve. In order to animate that bezier curve I have added hooked the curve with empties (ctrl+h used: https://blender.stackexchange.com/a/21234 )
Now I have selected my text and set up a Child Of constraint on the text and set the target to my BezierCurve ( https://blender.stackexchange.com/a/26109 ).
Now my problem: when I animate my bezier curve, I now have to grab the empties and move them around. The problem is that the bezier curve stays at its location, resulting in that the text doesn't move.
I always want that my text follows in the center of my curve at a fixed distance. But doesn't seems to work with the ctrl+h and child of constraint.
This is the result that I want after moving the curve. I moved the empties and manually set the text at the position, as the text didn't follow the curve by itself:
(note: I'm not so experienced yet with blender)
Update: The file I have so far:
Update 2: for now I've added a bezier curve, extruded it over the x-axis so that it doubles in length and has 3 'control points' (start, middle and end). Next I've added 3 hooks (ctrl+h) which generate 3 empties. After this I've added my text and added 2 constraints which attach on the middle Empty (hook): a childof and limit distance. Now I can animate by keyframing the 3 empties and dragging the empties to other locations. By dragging the empties the curve moves and the text also follows the middle empty. Could not find a better solution for now...
